Ayla's mother, Trista Reynolds, said this could be the last vigil she attends for Ayla so she can focus on raising her two young sons.

"It's not like I'm giving up or saying I'm done. It's just, simply I need to take a break for my family and just to stay focused on the next step to getting justice for Ayla," said Reynolds.

It has been more than two years since Ayla vanished from her father's Waterville home.

"It's been hard just thinking she'd be four years old. How beautiful she would be. What new things she'd be doing. How her, Raymond and Anthony would be playing together. Just a lot of things have been running through my mind today," said Reynolds.

Maine State Police have said they no longer believe she is alive.

The search has become the biggest criminal investigation in the state's history.

Police have never charged anyone with a crime related to Ayla's disappearance.
